Re: IO Problem

Is that the full code? I see function defined but not used, and functions called but not defined.

There may be no direction register like uou think; never worked with the 5000. Have you checked the manual? The info might be dispersed, but it should be out there. There used to be posters showing all registers of the processor, at least for the 3000.

This works fine, but as soon as I try to change the port from D to A the compiler thorws a bunch of errors. These errors are according to the portnames. But there is no such table inside the user manual.
